MP 1,1-5,1 Manually Configured OpenCore on the Mac Pro

Status
The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. Your edits will be public.
Thanks for the well detailed instructions.
I was wondering whether it is normal for the EFI partition to appear up as a boot drive in the boot picker screen, or did I do something wrong. The system boots correctly when I select it, but not when I select the Catalina drive (which also appears in the boot picker screen).
 
hey guys. I’m having this issue where Open Core just won’t stick after shutdown. It will boot normal without open core if cold booting. Once I do the Open Core command I can reboot with open core enabled. Anyone seen this before? Thanks

update: well I’ll be damned. Good old Pram reset fixed it.

I wonder, does HWaccel on Big Sur is working with the Lilu/Whatevergreen september update?

Activate AMD hardware acceleration

As expected, HWAccel still works in Big Sur. However, due to Lilu and WEG are not supported macOS 11 yet, DRM streaming won't work at this moment.

I haven't test the latest Lilu + WEG yet, but HWAccel works since beta 1.

Goodmorning, hope to not go OT since I have a problem on a beta OS (big sur PB6)
I recently changed the Sapphire Nitro+ RX590 on my Mac Pro 5,1 in signature with a Sapphire Pulse BE RX5600XT card.
I've had to update the device part of the OC config.plist but now on Catalina 10.15.6 both HDMI and Display ports are working just fine. The problem is on BigSur PB6 where (with the same OC 0.6.0 configuration) it works only if I connect the monitor to HDMI ports on the back (on display port I have black screen after boot).
I have updated both lilu and wethevergreen kexts to latest available version but I have the same behaviour.
I'll send you later my OC config for troubleshooting (now I'm at work:)
Thank you by now for your support!

Have a nice day

EDIT: Attached currently OC config.plist

I finally got my 6-core going with clean installs for both Mojave and Catalina. When I moved to my working 12-core, I tried every which way to get the recovery partition to boot, but no luck, no matter how long I waited. I pulled my SYBA card with 2 970s and used fresh install boots, and everything worked fine. I realized that I could just use Migration Assistant, to get all my apps back, but once it's complete, it wouldn't boot into Recovery for future Opencore updates. I forgot the name of the reinstall, but I simply reinstalled Mojave to my full (all the apps, certainly not the drive space). Once it finally booted into recovery, I just installed Catalina on the other 970 (diskA). Everything is working fine so far. Of course, Catalina doesn't have all my apps, but I'm much more inclined to use it on Catalina., now that the process is working fo me.
One problem that I have is cloning backups. Mojave comes out fine, but Catalina usually crashes SuperDuper!. How do others make clones for the Opencore drives?

Then this (I didn't expect you removed the no compat check boot argument, you shouldn't do that for Big Sur / Catalina)

Great! it works perfectly now!
Thank you for your hint... I think I have taken that disinformation somewhere when tried to install big sur the first time...
Now I'll compare and study the config.plists in order to understand what you have changed...
thank you again for your help

When I try to install Catalina, Even with a blank drive installed ready for it to be installed on, I get this error: "Your Mac needs a firmware update in order to install to this volume. Please select a Mac OS Extended (Journaled) volume instead.

I'm on Boot ROM version 144.0.0.0.0 already...

Any suggestions?

Additionally, if I format that drive as HFS+, it allows me to install, but on reboot I get "An error occurred while verifying firmware"

To all who replied to my request for help, thank you very much!

After checking a few things I realized that when I downloaded the OpenCore I didn't pick the right version, so the configuration file was wrong for the version I had.
When I opened the page the first time I assumed the version I needed was at the top of the page and away I went with that. In any case, it is all good now.
I downloaded the proper one and repeated the process and I am at the point now that I am downloading Catalina to then proceed to the installation.
Thanks again. I'll report back once it is up and running

Turn off SMBIOS spoofing if that still on.
 
Hi everyone, sorry if this is a dumb question but I couldn't manage to find an answer on this thread.
I'm new to opencore, and I successfully installed it (v. 0.6.1) on my dual CPU 5,1 using h9826790's config. Everything seems to work fine, except that my 144Hz monitor is now stuck to a maximum refresh rate of 60Hz. The monitor is a AOC 24G2U connected to a RX580 through DisplayPort. Disabling DirectGopRendering didn't changed anything.
Any idea? Thanks!

So without OC you get 144Hz with the same cables in Mojave?

Thanks for your reply! I forgot to mention that I was already under Catalina, installed with the compatible Mac method. I directly installed OC on the EFI partition of my Catalina install.
But basically yes, I had 144Hz recognised by default and working with the same cable and it disappeared since I installed Opencore.

I did a little bit of trial and error, and changing the "DP capability" setting in the OSD of the display to 1.1 and then reverting it back to 1.2 recovered the 144Hz setting in System Preferences. However, it is gone again after a restart... Not very convenient if I have to do this trick every time I boot the Mac.

Please try to boot to Catalina directly (e.g. by inserting the no compat check boot argument) to check if that's really OpenCore related.

Ok, so I deleted OpenCore, reseted the NVRAM, went into recovery with a Mojave backup drive to add no-compat-check, and went back to my main Catalina install... and it worked, the AOC is recognised as a 144Hz monitor straight away.
 
Anyone knows what is the easiest way to compare what options changed from a version to another, on acidanthera/OpenCorePkg repo?
[automerge]1600296023[/automerge]
 
The guide has been updated to OpenCore version 0.6.1.

Note that the configuration options for adding kexts has changed; Part II of the guide reflects this change.

Some help would be greatly appreciated. I've been running open core fine for a while now with great results. Recently, I haven't been seeing a boot screen even though I'm running a GTX680. I tried replacing my Open Core with the latest. Same thing. No boot screen.
